A lively technical debate from 1992 between Andrew Tanenbaum and Linus Torvalds discusses the merits of microkernel vs monolithic kernel architectures, with Tanenbaum advocating for microkernels while Torvalds defends his monolithic design choices in Linux based on practical implementation considerations.
The 6502 processor is recommended as an ideal starting point for learning assembly programming due to its simplicity with only 6 registers and 56 instructions, making core concepts easily digestible. Extensive learning resources and emulators are available through multiple platforms, though its practical applications are limited to retro programming.
